' v MACHINE FOR UNITING UPPERS TO SOLES.

SPECIFICATION forming part'of Letters Patent No. 247,998, dated October 4, 1881. Application filed July 14, 1ss1. (No model.)

a v To all whom it may concern:

Be it known that I, WILLIAM M., STEINLE, of the cityof Allegheny,in the county ofAllegheny and State of Pennsylvania,have invented anew and useful Improvement in Machines for Uniting Uppers to Soles; andI do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, forming a part IQ of this specification, in which Figure 1 is a side elevation of my improved machine for uniting uppers to soles. Fig. 2is a plan viewof the same. Fig. 3 is a plan View of the table. Fig. 4 is a plan view of the top of the holder or vice. Fig. 5 is a plan view of the bottom of the same, and Fig. 6 is a vertical section of the same on the line y y, Figs. 3 and 4. I

Like letters of reference refer to like parts 2o wherever they occur.

My invention relates to an improvement in machines for uniting uppers to soles of boots and shoes; and it consists of a clamp or holder for holding the upper on the last, and a pair of rollers for creasing and securing the upper of the shoe or boot to the insole, in combination with suitable mechanism for actuating the same.

' I will now describe my invention, so that 0 others skilled in the art to which it appertains may manufacture and use the same.

In the drawings, A represents the table attached to a frame, B. This table is provided with a longitudinal slot, C, through which passes a pin, D, having heads E, one above,

the other below, the table A.

In rear of the table A is a perpendicular standard, G, at the top of which is mounted a shaft, H, provided with band-wheels I J K.

livoted to the top of the standard Gis a horizontal frame, L, at the forward end of which are two shafts, M M, provided at their ends with band-wheels O P, and at their inner ends with rollers Q B, one of which, R, is provided 5 with athread,S, extending around the circumferenceof the same, while the roller Q is plain. The band-wheels I and O and K and P are connected by endless bands T T. The bandwheel K is smaller than the band-wheel Land the band-wheelP islarger than the band-wheel O,so as to give a morerapid motion to the fricvise or holder, V, the four perpendicular jaws or leaves of which are hinged to a-bottom board,

W, so that the sides and ends of the vise may be drawn together or separated at theirtop by geans of the two right-and-left-handed screws X X indicate the screws for operating the jaws of the vise. These screws are arranged to cross each other at rightangles,andare pro; vided with right-and-left hand threads extending from the middle of each screw to the ex tremities thereof. One of said screws controls the two side jaws, L L, and the other the heel and .toe jaws,so that the rotation of each screw causes two of the jaws to approach or recede from each other, as the case may be.

The sides and ends of the vise are cut away at the top, so as to form an opening of the shape of the sole of ashoe. To the end leaves or jaws, which constitute the front and rear of the opening thus formed,are bolted two ho1ders,A-B, lined with rubber or other suitable material, so as to gripe firmly the toe and heel of the last, and the side leaves or jaws, L L, may be also provided with rubber-lined holders,it' desired,

so as to the more effectually secure and sup- 1 port the shoe during the operation of the roll ers Q R.

In the bottom face of thebottom board, W, is a pattern slot or recess, C, in shape similar to the sole of a shoe. With the edge of this slot C the head E of pin 1) engages,thus providing a means for guiding the vise as it is moved about to present the shoe to the action of rollers Q R. From the rear of the frame B extends a rod, D, the other end of which is connected with a foot-lever, E.

Under the table A is a rod, F, one end of which is hinged to the standard G,'whi le the other end extends to the front of the table A and is held up by a spring, G. Near the middle of this rod, on the upper side of the same, is an inclined catch, H, which engages with the head F of pin 1), and holds the pin in a fixed position directly under the rollers Q, R,so that the pin may serve as a guide for the vise.

The operation is as follows: The vise V is placed on the table A so that the slot 0 in its bottom board shall be over the head E, Fig. 3, of the bolt orpin D. Theupperand insole ofthe shoehaving been placed on the last, the sameis placed in the vise V, the sole of the shoe being uppermost. The vise is then pushed forward, thepin D traveling in the slot (J until the shoe is brought directly under the friction-rollers Q R, and the head F, Fig. 1,0f the pin D has passed the catch H. Paste having been applied between the upper and insole ot'the shoe or boot, the edges of the upper are bentover theinsole. The friction-rollers Q R are then brought do wn on the sole of the shoe by the foot-lever E. Motion is applied to the main shaft, which causes the friction-rollers to revolve and thereby crease and smooth the edges of the upper on and to theinsole. The vise is movedaround, being guided by the head E of the pin D inthe guide-slot C, so that the friction-rollers shall operate on the entire edge of the uppers. The catch H holds the pin D stationary or fixed with relation to rollers Q R during the movement of the vise and the operation of the rollers. One object of mounting the friction-rollers and R on separate shafts is to allow of snfficient give to the rollers to enable them to work together on the uneven surface of the creased leather. The action of the roller It provided with the thread is mainly to crease and foldthe edges of the upper overtheinsole, while the rapidly-revolving roller Q smooths the work. Vhen the entire edge of the upper has been acted on by the rollers the catch H is released by pushing down the rod F, the vise is drawn forward and unloosened, the shoe is removed, anotherisjinserted, and the operation is repeated.

The advantages of my invention are the substitutionot' mechanical for manual labor in uniting soles to uppers of boots and shoes, and the great rapidity and excellence of the work resulting therefrom.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. In a machine for uniting soles to uppers of boots and shoes, one or more revolving rollers, adapted to press the edge of the turned upper down upon the inner sole, in combination with a vise for holding the shoe, substantially as and for the purpose specified.

2. In a machine for uniting soles to uppers of boots and shoes, a revolving roller or rollers, adapted to press the edge of the turned upper down upon the inner sole, and having a threaded surface, in combination with a vise for holding the shoe, substantially as and for the purpose specified.

3. In a machine for uniting soles to uppers of boots and shoes,arevolving roller having a threaded surface and arevolvingroller having a smooth surface, in combination with mechanism for imparting a more rapid motion to the smooth-faced roller than to the roller having a threaded surface, substantially as and for the purpose specified.

4. In a machine for uniting soles to uppers of boots and shoes, a vise or holder composed of a series of movable clampingjaws or leaves arranged around a common center, and adapted to be moved to and from each other by rightand-left-hand screws, in combination with a bottom board provided with a guide slot or channel adapted to receivethehcad of aguidepin upon the table of the machine, substantially as and for the purpose specified.

5. In a machine for uniting uppers to soles of boots and shoes, avise or holder having adjustable sides hinged to a bottom board, said bottom board havingapattern-recess on itslower face, in combination with a headed pin adapted to traverse a slot in the machine-table, a slotted working-table, and a catch for securing the movable pin, substantially as and for the purpose specified.

6. In a machine for uniting soles to uppers, the combination, with a pivoted or rocking frame and mechanism for raising and lowering the same, of two revolving rollers independentlyjournaled in the frame to permit them to operate on uneven surfaces, and a suitable support for the shoe, substantially as specified.

In testimony whereof I have hereunto set my hand. v

WILLIAM M. STEIN LE.
